Hodlers and traders are the ones that keeps the network going and the increase in price overtime. Hodlers rotation is inevitable because we must sell those coins someday. If we don't, when we pass on, the new owner that inherited your bitcoin will definitely sell. Selling is the only way to benefit from your bitcoin investment after a long time of holdi, and buying is the only way to own bitcoin. This makes hodlers rotation a must.
I think your comment is very important. Holders and traders keep the network active and contribute to price growth. However, while it is absolutely true that the rotation of holders is "inevitable", it is necessary to look at the context a little deeper. The nature of Bitcoin is not just "to be sold" - many see it as an alternative to fiat money, digital gold, or a means of future financial freedom. For this reason, holders do not plan to sell it, but rather keep it for future generations. You are right, holders have to sell at some point - this is the reality of the market. However, many see Bitcoin as a future-proof asset, not just a trading tool.
